Abstract

The aim of this work was to investigating the effect of foliar application of potassium (K) and the growth regulator Cycocel (CCC) on the physiological traits of maize (Zea mays L). The experiment was designed using a split-plot arrangement within a randomized complete block design (RCBD) with three replicates. The treatments included foliar application of potassium at concentrations of 500, 1000, and 1500 mg.L–1, as well as three concentrations of the growth regulator Cycocel (0, 150, and 200 mg.L–1). The results indicated a significant increase in Protein (P), phosphorus, and carbohydrate contents at the concentration of 200 mg.L–1 of Cycocel, reaching 8.22%, 0.71%, and 199.46 mg g–1, respectively. Biological reason for the observed decrease in leaf nitrogen percentage with increasing Cycocel concentrations by spry ratio. A significant decrease in nitrogen percentage in the leaves was observed with increasing concentrations. The results also showed no significant differences due to potassium application in all physiological traits except for carbohydrate content, which significantly increased at the concentration of 1500 mg.L–1, reaching 214.35 mg.L–1. For future work use different concentrations of K and the growth regulator CCC, depend on the spry ration, apply both to soil and as foliar sprays on different maize cultivars, investigate the effects of potassium and CCC on other cereal crops.
